# 3. Convert to float range [0, 1] binary = binary / 255.0
Standard SDFs struggle with sharp corners (like the tip of a star). If you need perfect vector quality, look into MSDF (Multi-channel SDF). Converting PNG to MSDF requires specialized tools like msdfgen . The Result: Perfect Scaling Once converted, you can render your SDF in a shader like this (GLSL snippet): convert png to sdf
# 2. Normalize to binary (0 or 255) _, binary = cv2.threshold(img, 127, 255, cv2.THRESH_BINARY) binary = cv2.threshold(img
# 6. Normalize SDF to 0-255 range for storage sdf_normalized = (dt / dt.max()) * 255 sdf_normalized = sdf_normalized.astype(np.uint8) convert png to sdf
